MILWAUKEE (CBS 58) -- In January, CBS 58 introduced you to Brian Cox. The Milwaukee firefighter was diagnosed with Hodgkin's lymphoma in 2016 and needed a bone marrow transplant to survive.

CBS 58 has learned Cox received his transplant from his sister Thursday and that while his loved ones are bracing for the possibility of tough side effects, they're hopeful for a fast recovery.

The huge grassroots search for bone marrow donors that Cox inspired is continuing on Sunday, March 4.

The Blood Center of Wisconsin will have a booth at UWM Panther Arena during Battle of the Badges.

Just show up, fill out some paperwork, take a cheek swab and you'll be entered into a national database that can save a life.

"It's all about awareness and education. That's where it all begins. There are many misconceptions about donating bone marrow, mainly that it's a painful procedure. It's actually quite simple. Just to have the venue of Battle of the Badges to get behind our message and get the correct information into people's hands so they can decide it's what they want to do is so important to us," says Danielle Savick with the Blood Center of Wisconsin.
